Abstract

The aim of this project is to develop a soil NPK sensor that uses an Arduino board and OLED display to detect the levels of nitrogen, phosphorus, and potassium in soil. This device is designed to help farmers improve crop fertility and increase productivity by providing real-time data on soil nutrient content. The sensor is inserted into the soil and contains a probe that measures the nutrient content. The Arduino board activates the sensor and sends the data to the OLED display for easy reading. The device also uses an interface module to connect the sensor to the Arduino. This technology has the potential to revolutionize the way farmers approach soil management by allowing for precision agriculture and efficient use of fertilizers. The NPK sensor is a faster and more convenient alternative to traditional laboratory techniques for measuring soil nutrient levels, and could help farmers to improve crop yields and soil fertility.
